JAMES A. ASHLEY-REAVIS, OF DENVER, COLORADO.

WEIGHING MEANS OR SCALE FOR WAGONS.

1 b all whom it may concern:

Be it known that I, Janus AnmsoN AsH- LEY-REAVIS, a citizen of theUnited States, residing in the city and county of Denver, in the Stateof Colorado, have invented a new and useful Weighing Means or Scale forVagons, of which the following is a specification.

My invention relates to improvements in weighing machines or scales,which constitute a means of weighing by a system of levers fulcrumedupon a wagon whose bed or body is detachable from the running gear inorder that such bed or body may be employed as a platform. for thescales to be lifted by the action of said levers with the load it isdesired to weigh and the weight indicated upon a central beam, fulcrumedupon such bed or body.

The leading features of my invention are involved in a combination oflevers and supports which have curved pivotal surfaces and which areattachable to the wagon and detachable therefrom at pleasure, thisresult being obtained by the use of a few bolts, and without anyaddition to, or change in, an ordinary farm wagon to which the scalesare attached.

I will now proceed to describe the invention in connection with theaccompanying d 'awings, realizing that there are various possibilitiesof variation therefrom, and it is understood that the invention islimited only by the appended claim.

In the drawings forming part hereof Figure 1, is a side elevation of acommon farm wagon with my weighing means attached thereto. Fig. 2, is atop plan in part illustrating my weighing means as it appears upon theleft-hand side only of the wagon. Figs. 3 and 1, represent sideelevations only of one of my bolster standards and the casing therefor,this casing being shown in section in Fig. 3, and the twist shaftsimilarly so shown in Fig. 4, the wagon bed with the casing being shownin both views raised as when the scale is in action. Fig. 5, representsa face view of the standard casing, the bolster and standardSpecification of Letters Patent.

being shown in dotted lines. Fig. 6, represents a cross-section of thescale beam as shown in Fig. 1, on the line 6-43. Fig. 7, represents across-section of the fulcrumbracket upon the line 7-7. Fig. 8,represents a partial section upon the line 8-8. Fig. 9, represents asection of a detail shown in Fig. 1, upon the line 9 9, showing therollers and push-block. Fig. 10, represents a different view in sectionof the device shown in Fig. 9, partly broken away. Fig. 11, represents aperspective view of my main fulcrum block detached, this support beingadapted to be secured to the bolster. Fig. 12, represents my pivotsleeve in perspective. F ig. 13, represents my twist shaft inperspective showing a pair of fulcrum levers connected thereto. Fig. 14,represents my fulcrum block and lever when out of action.

My invention includes a system of levers for weighing purposes, the samebeing attachable to an ordinary farm wagon without substantial change inany part thereof, as shown in F igs. 1 and 2, wherein the wagon bed a,is used as a platform for my weighing scales.

The running gear of the wagon includes axles 7), Z), with wheels 0, c,and the bolsters (Z, (Z, the latter serving as supports for standards E,E. Casings g, 9, upon the bed engage the standards normally, as shown inFig. 14:, and are disengaged automatically when the bed is elevated andthe scale is in action; since the outwardly projecting flanges g, g, andcontact faces f, f, of the casings are sloped upwardly toward thestandards, the latter being provided with opposing faces correspondinglyinclined. The standards may be provided With a sheathing of iron asshown at e.

The running gear of the wagon is provided with fulcrum blocks H-H,secured to the sides of the bolsters 0?, cl. These fulcrum blocks areeach preferably provided with two surfaces h, it, at right angles to oneanother, and which rest respectively on the lateral and upper faces ofthe bolsters, to which the blocks may be secured by bolts or screws, asshown. Each fulcrum block is provided with a slightly convex bearingsurface 71/, upon which when the scales are brought into action, restthe convex fulcrum bearing surface j, of one of the fulcrum levers J.The other convex surface j, of each of these levers is brought, when thescales are in action, into contact with the curved bearing surface ofone of the push-blocks 0, connected to the underside of the wagon bodythrough housing F, in which the block is movably mounted, the housingfor this purpose being provided with a chamber f, into which thepushblock loosely fits. Rollers P, P, are placed between the upper wallof this chamber and the upper surface of the push-block, this surfacebeing provided with concavities g, to receive the rollers. The blocksare retained in the housings by plates 7, detachably secured to thelower face of the housings. It will be understood that two of theseblocks are provided at each end of the wagon body and that the fulcrumlevers that cooperate therewith are connected by means of the usualtwist shaft K, to one end of which is connected also the first reductionlever Z. The pairs of housings at either end of the body are connectedby a T-rail S, (Fig. 9), secured to the underside of the body and to thehousings at opposite sides of the body by means of lugs q, on thehousings, which are provided for this purpose. Each housing is alsoprovided with a flange q, secured to the side of the wagon body. Thereduction levers Z, at the front and rear of the body are connectedthrough yoke y and knife edge 11, yoke and knife edge 41, links a, a,respectively, with the second reduction levers m, m, respectively,pivoted in fulcrum brackets u, adjustably secured to the side of thewagon body by means of bolts or screws inserted through horizontal slotsat the upper and lower extremities of the brackets. Lever m carries acounterweight m The levers m, m, are connected by means of a rectangularstirrup 6, which consists of a straight front piece 6, and a back piece6, the latter having two forwardly projecting arms, one of which ishinged to the front piece at its upper end and the other detachablyinterlocked with said piece at the lower end, which is provided for thispurpose with an aperture adapted to receive the crooked extremity of thesaid lower arm. These front and rear pieces are provided with openingsto receive the pivots of the levers m, m, these pivots being preferablycarried by pivot sleeves 12, which are adjustably connected to thelevers by being sleeved thereon, and are held in position by set screwsas shown in Fig. (3, this construction being preferably employed for allof the pivots of each of the levers mounted on the side of the wagonbody. The pivot sleeves 12 are connected to the stirrup and back pieceby the knife edge parts o and o.

The weigh beam V, is connected to the above-mentioned stirrup (3, bymeans of the swivel rod N, connected to the yoke 2, the latter beingprovided at its lower extremity with openings for the pivots *0 of thelever lV, which is fulcrumcd in bracket 7, adjustably mounted on theside of the wagon body in the same manner as are the brackets a. Thebearings for the knife edges in these brackets are preferablyconstructed, as shown in Fig. 7, with seats for the knife edges 1/formed by the openings, that in the outer arm being closed by means of aplate :0, having a conical recess in its inner face, the largestdiameter of this recess being substantially that of the seat openings. Alike concavity may be formed in the other arm of the bracket, as shownat a). The knife edges are preferably at their ends provided withsurfaces inclined from the contact edges toward the sides of the levers,as shown in Fig. 7. By this construction grinding action of the ends ofthe knife edges against the adjacent edges of their seats is avoided.The beam V, is provided with the usual guard 16, which limits its swing,and with the usual weighing counterpoises w and lVhen the scale is to bethrown out of action the lower end of the front plate 6, is disengagedfrom the forwardly projecting end of the rear plate 6, of the yoke 6,which may then be removed from the levers m, m. The latter are then freeto rise and the wagon body will thus be lowered until it rests upon thebolsters, and, upon further upward movement of said lever, the surfacesj, will become disengaged from the blocks 0, and the levers Z, Z, withtheir connected parts are then free to assume any position so long ascontact surfaces 7', of the fulcrum levers rest upon the fulcrum blocksH. In the actual weighing operation, however, I prefer to have theselevers so adjusted that the surfaces j, are in contact with the convexsurfaces 71., of these blocks.

To prepare for weighing action, the levers m, m, must be forced down,and the stirrup 6, replaced thereon. The lever TV, may be incased in asuitable box or receptacle B, which may be secured to the side of thewagon body and may be provided with a door B, as shown.
